Abstract

The invention relates to a projection switching system and a projection switching method for teaching. The projection switching system comprises at least one teacher terminal, at least one student terminal, at least one converter, at least one projector and a campus wireless network. The teacher terminal is connected with the converter through a video wire and sends a wired projection request to the converter. The student terminal is used for sending a wireless projection request to the converter through the campus wireless network. The converter receives and transmits the wired projection request sent by the teacher terminal and the wireless projection request sent by the student terminal to the projector. The projector correspondingly achieves teacher terminal wired projection or student terminal wireless projection. According to the projection switching system and the projection switching method, whether a wired connection or a wireless connection is carried out, the projection can be used only through the connection of a local area network, practicality is achieved more, better interaction can be achieved in a teaching process, and teaching quality is improved.

Description

technical field

[0001] The invention relates to the field of teaching management equipment, in particular to a projection switching system and projection switching method for teaching. Background technique

[0002] At present, in multimedia teaching, teachers can display their own presentations through the multimedia function of the projection device. However, on the student side, they are still not out of the passive acceptance state of blackboard teaching. There is a lack of a public information terminal between teachers and students, and among students, to realize the interaction in teaching. For example, in a programming class, the teacher had to go to the students' machines to guide them in order to solve the students' problems. In the existing teaching management software, computer room management software such as Starscream manages according to the number of the computer in the computer room. Students choose seats randomly during class, and the teacher does not know...

Embodiment Construction

[0034] The principles and features of the present invention are described below in conjunction with the accompanying drawings, and the examples given are only used to explain the present invention, and are not intended to limit the scope of the present invention.

[0035] Such as figure 1 As shown, this embodiment provides a projection switching system for teaching, including: at least one teacher terminal 1, at least one student terminal 2, at least one converter 3, at least one projector 4 and campus Wi-Fi 5;

[0036] The teacher terminal 1 is connected to the converter 3 through a video cable, and is used to send a wired projection request to the converter 3 .

[0037] The student terminal 2 is connected to the campus wireless network 5 through a built-in wireless access module, and is used to send a wireless projection request to the converter 3 through the campus wireless network 5 . The wireless access module may use a wireless network card in practical applications. ...
